Administrators are Wikitravellers who have been nominated by the Wikitravel community and have been granted some additional privileges over and above normal. Administrators have shown a good appreciation of the Wikitravel policies and guidelines and made significant contributions on Wikitravel articles.
The main features available only to administrators are:
The decision to give these privileges to certain users is pragmatic. Most vandalism and other changes that don't conform to policy can be reverted or changed by any serious Wikitravellers. Protection and deletion cannot; therefore, these privileges are only granted to certain users.
Note that plenty of longtime Wikitravellers may not want the responsibility of being an administrator. Administrators are the plumbers and janitors of Wikitravel, and are asked to help perform some mundane tasks.
It's also important to remember that any user can edit, change, redirect, move, or otherwise muck with almost any article on Wikitravel. It's not really necessary to wait for an administrator to do some "administrative" work; in fact, it's best to just plunge forward and do the job yourself.
Becoming an administrator
If you think a Wikitraveller – including yourself! – should become a Wikitravel administrator, post their name on the administrator nominations page with a brief description of why the Wikitraveller should have administrator privileges. Include some evidence of understanding and experience with community policies.
If after 14 days of discussion:
a bureaucrat will grant them admin status.
There are no carved-in-stone requirements, but the following are generally considered advantageous:
Administrators are not expected to spend all their waking hours working on Wikitravel; if anything, taking long vacations to travel around is encouraged!
Administrator status is not a reward; the admin role simply indicates that the Wikitravel community feels that a user has a good understanding of Wikitravel's policies,
Ending administrator privileges
Unused high-privilege user accounts are a security risk. For this reason, administrators who don't use their user accounts for two years will be notified by email and their privileges will be revoked. Administrators who know they don't have the time or interest to continue as admins should request to have their privileges revoked voluntarily.
Administrators who abuse their privileges can have those privileges revoked via nomination.
After losing admin privileges for any reason, a Wikitraveller must go through the nomination process again to regain those privileges.
